Early A-Body Windshields, good purchase!
Bill,
There was gray butyl calk under the rubber seal when I took it out 34 years ago. I cleaned it out, and used silicone under the seal by inserting the nozzle, and going around. It did not show, or leak, but it was a pain to clean up this time.
I drove the car today, what a difference. Better tha new glasses.
